P150 STRESS–REST DYNAMIC–CT MYOCARDIAL PERFUSION IMAGING IN THE MANAGEMENT OF MYOCARDIAL BRIDGING: A “ONE–STOP SHOP” EXAM

Abstract Myocardial bridging (MB) is a congenital anomaly characterized by intramyocardial coronary course that can cause compression during systole and lead to myocardial ischemia. The improvement in computed tomography (CT) scanner technology has increased the detection of MB coronary–CT (cCT) exam but assessment their functional significance often challenging. Tha stress–rest perfusion imaging (MPI) single–photon emission CT (SPECT) required decide patient’s management after anatomical evaluation with cCT or Invasine Coronary Angiography (ICA). However, SPECT long acquisition protocols, poor spatial resolution, anatomical/Functional protocols expose patients significant radiation doses. Thus, dynamic–CT MPI cCGT represent valid alternative. We report cases seven which we detected MBs evaluated using correct management. Three showed reversible defect left anterior descending (LAD) territory segments involved they were referred for treatment. remnants four LAD revealed normal conservatively managed. In all results stress completely overlapping, study longer process. allowed detect evaluate “one–stop shop” exam.
